Frequently Asked Questions
What are the body dimensions of the SFM-118-L2-SM-D and how do they affect PCB layout?
The SFM-118-L2-SM-D has a body length of 1.055 inch, body depth of 0.185 inch, and body breadth of 0.145 inch. These compact dimensions, combined with the 0.050" (1.27 mm) pitch dual-row layout, make the connector suitable for space-constrained PCBs where fitting 36 signal positions within a small footprint is a priority.
Why does the SFM-118-L2-SM-D use gold-plated contacts on the mating side but tin-nickel on the termination side?
Gold plating on the mating surface provides low contact resistance, excellent corrosion resistance, and extended cycle life across thousands of mating insertions. Tin-Nickel (Sn-Ni) on the termination side is optimized for reliable solder joint formation during SMT reflow at up to approximately 260°C, balancing cost and performance for each function.
Is the SFM-118-L2-SM-D RoHS compliant and suitable for lead-free manufacturing?
Yes. The SFM-118-L2-SM-D is marked as Pb-free (RoHS compliant) per its published specs. Its Tin-Nickel termination finish is lead-free, making it compatible with lead-free reflow soldering and qualifying for programs requiring RoHS-compliant 36-position board connectors in end products sold in the EU and other regulated markets.
How does the 0.050" pitch of SFM-118-L2-SM-D compare to .100" pitch connectors for board-space savings?
At 0.050" (1.27 mm) pitch, the SFM-118-L2-SM-D uses approximately half the linear board length of a comparable .100" pitch 36-position connector. This translates directly to PCB real estate savings, allowing designers to place more functional circuits alongside a 36-pin dual-row connector in the same board area used by coarser-pitch alternatives.
